Description

  The present invention relates to a unit type curtain wall in which a curtain wall unit is attached to a building frame continuously in the vertical and horizontal directions.

Conventionally, in a unit type curtain wall in which a curtain wall unit with a panel body mounted on a frame body is continuously attached to the building frame vertically and horizontally, the vertical frame on either the left or right side of the frame body has decorations, gondola rails, etc. For this reason, a projecting portion has been proposed.
For example, as disclosed in Patent Document 1, a unit-type curtain wall in which a decorative edge is provided on one of the left and right vertical frames of a frame has been proposed.
JP-A-7-113279

The above-described conventional curtain wall receives a load in the out-of-plane direction (inner side of the room) due to strong wind and rain or a gondola, and the vertical frame of the frame body may bend in the out-of-plane direction by this load.
Since one vertical frame of the frame has a decorative edge, the out-of-plane rigidity is stronger than the out-of-plane rigidity of the other vertical frame. Is smaller than the amount of deflection in the out-of-plane direction of the other vertical frame.
On the other hand, in the curtain wall unit adjacent to the left and right, one vertical frame having a decorative edge and the other vertical frame having no decorative edge are adjacent to the left and right.
For this reason, when the curtain wall receives a load in the out-of-plane direction, a displacement difference in the out-of-plane direction occurs in the vertical frames adjacent to the left and right.
In other words, since the amount of deflection in the out-of-plane direction of the vertical frame that does not have a decorative edge is greatly displaced in the out-of-plane direction, the amount of deflection in the out-of-plane direction of the vertical frame that has a decorative edge is small, so The displacement is small and a displacement difference in the out-of-plane direction occurs.

  As described above, when a displacement difference in the out-of-plane direction occurs in the vertical frames adjacent to the left and right, the watertight performance between the vertical frames adjacent to the left and right may be deteriorated.

  An object of the present invention is that when the curtain wall receives a load in the out-of-plane direction, a difference in displacement in the out-of-plane direction occurs between the vertical frame having the protrusions adjacent to the left and right and the vertical frame having no protrusions. It is to make the curtain wall so that there is no.

The present invention is a curtain wall in which a plurality of curtain wall units each having a panel body attached to a frame body are continuously attached to a building frame vertically and horizontally,
Each frame includes a left and right vertical frame having a protruding portion and a left and right vertical frame not having a protruding portion, and a frame adjacent to the left and right has a vertical frame and a protruding portion having the protruding portion. A vertical frame that does not have
The curtain wall is characterized in that the vertical frame having the protrusions adjacent to the left and right and the vertical frame not having the protrusions are connected so as not to move relatively in the out-of-plane direction by a locking part.

In the present invention, the locking part includes a first bracket that has a protrusion and is attached to one of the left and right vertical frames, and a second bracket that is attached to the other left and right vertical frames,
The first bracket and the second bracket can be fitted and connected so as not to move in the out-of-plane direction.
In this way, since the bracket of the locking part and the bracket for mounting the protruding part to the vertical frame are combined, the number of parts is small and the mounting work of the locking part and the protruding part to the vertical frame is easy.

In the present invention, the locking component includes a first bracket attached to one of the left and right vertical frames, and a second bracket attached to the other left and right vertical frames, and the first bracket and the second bracket are in the in-plane direction. Fit so that it does not move in the out-of-plane direction by moving,
Sealing materials that are pressed against each other by moving in the in-plane direction can be attached to the left and right vertical frames and the left and right vertical frames, respectively.
In this way, after attaching the left and right curtain wall units to the building frame, the left and right curtain wall units are moved toward the left and right sides and attached to the building frame, While the second bracket is connected, the sealing material is in contact with each other, and the space between the left and right vertical frames can be sealed.
Therefore, it is easy to attach the curtain wall unit continuously in the left-right direction.

In the present invention, the first bracket has a concave portion opened in the in-plane direction, the second bracket has a convex portion directed in the in-plane direction,
By fitting the concave and convex portions, they can be connected so as not to move in the out-of-plane direction.
If it does in this way, the vertical frame which has a projection part by the fitting of a convex part and a crevice, and the vertical frame which does not have a projection part can be firmly connected so that it may not move to an out-of-plane direction relatively.

According to the present invention, when the curtain wall receives a load toward the out-of-plane direction, the vertical frame that does not have the protrusions adjacent to the left and right is larger than the vertical frame that has the protrusions in the out-of-plane direction. However, since the two vertical frames described above cannot move relative to each other in the out-of-plane direction due to the locking parts, the two vertical frames described above bend by the same amount in the out-of-plane direction.
Therefore, a displacement difference in the out-of-plane direction does not occur between the vertical frame having the protrusions adjacent to the left and right and the vertical frame having no protrusions.

As shown in FIGS. 1 and 2, a plurality of curtain wall units 1 are continuously attached to a building housing 2, for example, a floor slab, with fasteners 3 vertically and horizontally to form a unit type curtain wall.
In the curtain wall unit 1, a panel body 5 is attached to a frame body 4.
The frame 4 has a left vertical frame 10, a right vertical frame 11, an upper horizontal frame 12, a lower horizontal frame 13, and an intermediate horizontal frame 14 connected in a square shape.
The upper portions of the vertical frames 10 and 11 are attached to the building frame 2 with fasteners 3.
The lower horizontal frame 13 and the upper horizontal frame 12 which are adjacent to each other in the vertical direction are connected by a connecting part 8 so as not to move relatively in the out-of-plane direction (inside of the room).
The connecting part 8 includes a first part 8a having an upward protrusion and a second part 8b having a downward recess, and the protrusion of the first part 8a and the recess of the second part 8b are fitted together. Then, connect them so that they do not move relative to the out-of-plane direction.
The left vertical frame 10 has a protrusion 20, and the right vertical frame 11 does not have a protrusion 20.
The panel body 5 is glass or a panel, but may be a shoji that can be freely opened and closed.

In the curtain wall units 1, 1 adjacent to the left and right, a locking part 30 is attached across the left vertical frame 10 and the right vertical frame 11 adjacent to the left and right. 10 and the right vertical frame 11 are connected so as not to move relatively in the out-of-plane direction (outside of the room).
The locking parts 30 are attached to a plurality of positions spaced in the longitudinal direction (vertical direction) of the vertical frame. This position and number are arbitrary.

  As such, when the curtain wall receives a load in the out-of-plane direction, the right vertical frame 11 without the protrusion 20 is larger in the out-of-plane direction than the left vertical frame 10 with the protrusion 20. Although the left and right vertical frames 10 and 11 are connected by the locking part 30 so as not to move relatively in the out-of-plane direction, the surfaces of the right vertical frame 11 and the left vertical frame 10 are intended. The amount of deflection in the outward direction is the same, and no displacement difference in the out-of-plane direction occurs.

As shown in FIG. 3, the locking part 30 includes a first bracket 31 having a protruding portion 20 and a second bracket 32 fitted to the first bracket 31 so as not to move in the out-of-plane direction. Yes.
The first bracket 31 is fixedly attached to the out-of-plane outdoor side portion of the left vertical frame 10 so as not to move in the out-of-plane direction, and the protruding portion 20 is more out-of-plane than the left vertical frame 10. It protrudes to the outdoor side.
The second bracket 32 is fixedly attached to the outdoor side of the right vertical frame 11 in the out-of-plane direction so as not to move in the out-of-plane direction.

Thus, since the first bracket 31 of the locking part 30 also serves as a bracket for mounting the protruding part 20 to the vertical frame, the number of parts is small, and the mounting work of the locking part 30 and the protruding part 20 is simple. .
There are a plurality of brackets (e.g., eight brackets) for attaching the protruding portion 20 to the vertical frame (e.g., eight brackets). It is as.

The first bracket 31 and the second bracket 32 are fitted so as not to move in the out-of-plane direction by relatively moving in the in-plane direction (left-right direction along the panel body 5).
It should be noted that the fitting so as not to move in the out-of-plane direction may be a case where it does not move in the out-of-plane direction at all, but also includes a case where it moves slightly in the out-of-plane direction in consideration of workability.
For example, the 1st bracket 31 has the recessed part 31a opened to the in-plane direction, and the 2nd bracket 32 has the convex part 32a which goes to an out-of-plane direction.

A primary seal material (rain barrier) 6 is attached to an intermediate portion in the out-of-plane direction of the vertical frames 10 and 11, and a secondary seal material 7 is attached to an indoor side portion in the out-of-plane direction.
The primary seal material 6 and the secondary seal material 7 are also attached to the upper cross member 12 and the lower cross member 13, which are continuously attached around the frame 4.
The primary sealant 6 and secondary sealant 7 of the left vertical frame 10 adjacent to the left and right and the primary sealant 6 and secondary sealant 7 of the right vertical frame 11 are in contact with each other in the in-plane direction and adjacent to the left and right. The left and right vertical frames 10 and 11 are watertight.

As such, after the left and right curtain wall units 1 are attached to the building housing 2, the left and right curtain wall units 1 are moved in the in-plane direction and the first and second brackets 31 and 32 are fitted. At the same time, the primary sealing material 6 and the secondary sealing material 7 can be attached so as to contact each other.
Therefore, the operation | work which attaches the curtain wall unit 1 continuously in the left-right direction is easy.

  In addition, when the curtain wall receives a load in the out-of-plane direction, the engaging part 30 prevents the left and right vertical frames 10 and 11 from causing a displacement difference in the out-of-plane direction. Since the secondary sealing material 7 is always in contact without shifting in the out-of-plane direction, the watertightness between the vertical frames adjacent to the left and right is not lowered.

Next, the protrusion 20 and the locking part mounting part will be described in detail.
As shown in FIG. 3, the left and right vertical frames 10 and 11 are provided in a substrate 15 facing in the out-of-plane direction, a mounting portion 16 provided on the indoor side of the substrate 15 in the out-of-plane direction, and an intermediate portion in the out-of-plane direction. Further, the first and second sealing material attaching portions 17 and 18 and the bracket attaching portion 19 provided on the outer side in the out-of-plane direction are the same cross-sectional shape.

The projecting portion 20 has a hollow portion in which the first plate 21 and the second plate 22 facing in the out-of-plane direction are integrally connected by a plurality of connecting pieces 23, and a long length having a gondola guide portion 24 on the outdoor side portion. It is a material.

As shown in FIG. 4, the bracket mounting portion 19 is provided in the middle of the first outwardly facing piece 19a and the second outwardly facing piece 19b facing outward in the in-plane direction, and between the first and second outwardly facing pieces 19a and 19b. The first and second support pieces 19c and 19d are opposed to each other.
The first bracket 31 has a substantially U-shaped vertical frame attachment portion composed of an attachment piece 33 directed in the out-of-plane direction and first and second outward pieces 34 and 35 provided at both ends of the attachment piece 33 in the out-of-plane direction. 36 and a projecting portion attaching portion 37 provided on the vertical frame attaching portion 36 (second outwardly facing piece 35), and the projecting portion attaching portion 37 is fixedly attached to the connecting piece 23 of the projecting portion 20 with a bolt 38. It is.
The mounting piece 33 fits between the first and second outwardly facing pieces 19a and 19b, contacts the first and second support pieces 19c and 19d, and the bolt 39 is screwed from the mounting piece 33 to the back plate 40. The back plate 40 is in contact with the first and second support pieces 19 c and 19 d, and the vertical frame attachment portion 36 of the first bracket 31 is attached to the bracket attachment portion 19 of the vertical frame 10.

The second bracket 32 includes a mounting piece 41 that extends in the out-of-plane direction, and first and second outward pieces 42 and 43 that are provided on the mounting piece 41 and extend outward in the in-plane direction. Are attached to the back plate 45 so that the first and second support pieces 19c and 19d are sandwiched between the back plate 45 and the mounting piece 41.
The first and second outward pieces 42 and 43 are the above-described convex portions 32a, and are fitted between the first and second outward pieces 34 and 35 (the aforementioned concave portion 31a) of the first bracket 31.
Since the first and second brackets 31 and 32 are made of metal, a metal squeak noise may be generated when they are in direct contact with each other, so that the first and second outwardly facing pieces 42 and 43 of the second bracket 32 are not connected to the first and second brackets 31 and 32. A shock-absorbing material 46 made of a metal member, for example, rubber packing, is attached, and the shock-absorbing material 46 is in contact with the first and second outwardly facing pieces 34 and 35 of the first bracket 31.

In the above-described embodiment, the first bracket 31 is separated from the projecting portion 20, but may be integrated.
The bracket for attaching the protruding portion 20 to the vertical frame 10 and the first bracket 31 of the locking part 30 may be separate parts.
